   • Event-Driven Programming Paradigm in Logic Programing

     Event-driven programming should be similar to how it is done in other languages, you would set up some framework to generate the events and you would call a goal to handle the event, possibly using the system's multithreading facilities (which leads to interesting aspects of transactions on the Prolog database, global vs. thread-local storage etc.)

     Paulo Moura would certainly provide this link to the Logtalk Manual:

     Also this paper comes to mind:

     I tried to develop something that uses prolog's syntax, approach and backtracking in python to solve the issue. I wrote pytholog library. I am sharing the answers to get comments and if there are better ways to do it.

     In pytholog I initiate a knowledge base and I query it.

     import pytholog as plfriends_kb = pl.KnowledgeBase("friends")friends_kb([ "has_lot_work(daniel, 8)", "has_lot_work(david, 3)", "stress(X, P) :- has_lot_work(X, P2), P is P2 / 100", "to_smoke(X, Prob) :- stress(X, P1), friends(Y, X), influences(Y, X, P2), smokes(Y), Prob is P1 + P2", "to_have_asthma(X, 0.3) :- smokes(X)", "to_have_asthma(X, Prob) :- to_smoke(X, P2), Prob is P2 * 0.25", "friends(X, Y) :- friend(X, Y)", "friends(X, Y) :- friend(Y, X)", "influences(X, Y, 0.4) :- friends(X, Y)", "friend(peter, david)", "friend(peter, rebecca)", "friend(daniel, rebecca)", "smokes(peter)", "smokes(rebecca)"])print(friends_kb.query(pl.Expr("to_smoke(Who, P)")))# [{'Who': 'daniel', 'P': 0.48000000000000004}, {'Who': 'david', 'P': 0.43000000000000005}]print(friends_kb.query(pl.Expr("to_have_asthma(Who, P)")))# [{'Who': 'peter', 'P': '0.3'}, {'Who': 'rebecca', 'P': '0.3'}, {'Who': 'daniel', 'P': 0.12000000000000001}, {'Who': 'david', 'P': 0.10750000000000001}]

   • logic programming - find synonyms of a given word

     Top Answer

     Answered Apr 09, 2021 · 1 votes

     In general, this just looks like you are interested in the transitive closure (of a graph)?

     For undirected graphs ("Being synonyms doesn’t depend on order"), this is related to Connected Components (and here we directly see some logic-relation as 2-SAT algorithms also exploit connected components).

     Maybe see also: Algowiki

     Basically:

     • preprocessing-time: calculate the transitive closure of your input
     • query-time -> synonym(a,b): check if edge (a,b) exists

     Or without preprocessing: just look for a path on-demand:

     • query-time -> synonym(a,b): check if there is a path between a, b BFS/DFS

     A simple method to generate some solutions is to pick a first row arbitrarily and then fill out each subsequent row by taking one minus the previous row. We can also do this with columns.

     It turns out that every valid matrix is generated by one of these two variants (note that the two perfect checkerboards are generated by both). The reason is that if the first row has adjacent zeros or adjacent ones, then the entries below it are forced, these force the rest of the row to be one minus the previous row, and in turn the rest of the rows are forced. Ditto columns. If neither the first row nor the first column has a duplicate, then we have one of the two checkerboards.

     Maximizing isn't too hard. For alternating rows, decide for each column whether the even rows or the odd rows are more valuable. For alternating columns, decide for each row whether the even columns or the odd columns are more valuable. Take the best of these two solutions.
